**Description**  
Using our developer client id and secret, everything works fine. When we switch to our production client id and secret, we’re getting a Client Id Mismatch error when trying to get an access token.

**Error**  
reason":“Invalid request : Client ID mismatch”,“error”:“invalid\_client”}

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
OAuth

**Which Endpoint/s?**  
getting access token

**How To Reproduce (If applicable)**  
Our app is called Digital\_Rural. We’ve double checked that the Authorization header is using the production client id and secret. The publishable URL is using the production client id, the api call is using the production client id.

**Additional context**  
How should we proceed with fixing this?
